Many business-to-business (B2B) marketers use loyalty cards to recognize their loyal customers and give them benefits for their continued patronage. A B2B customer typically has a single corporate account with the seller. But, the customer often wants multiple loyalty cards that it can distribute to its employees who will be using the seller’s product and services for earning loyalty points. The loyalty cards points are often accrued over varying time frames and sometimes cards become inactive or lost and need to be replaced. Problems arise in consolidating loyalty points in situations where cards are anonymous and lost or inactive cards are simply replaced by new ones. We develop and report a SAS Macro to solve this problem
